- Salt-Dependence of Homology Searching Step by RecA Nucleoprotein Filaments

We applied lateral magnetic tweezers to stretch duplex DNA molecules (Lambda DNA, 48,502 bp) in order to monitor the homology searching step by RecA nucleoprotein filaments at the single-molecule level. From individual searching events, the diffusion coefficient of the RecA nucleoprotein filament is determined to be ∼ 0.5-1 μm2/s. The nearly salt-independence of the diffusion coefficients of RecA nucleoprotein filaments implies that our observed RecA searching events were mainly carried out by the one-dimensional sliding mode.

Highly dispersed palladium nanoparticles were prepared by using aqueous extract of Astraglmanna, a non-toxic and eco-friendly material, without extra surfactant, capping agent, and template. The palladium nanoparticles were characterized using UV–Vis spectroscopy, (SEM-EDX), (FTIR), (DLS) and (XRD) analysis. The obtained results confirmed The presence of well dispersed nano-scale palladium particles ranging from 5-25 nm.
- Electrochemical Behavior and Determination of Phenylephrine at Silicate Nanotubes Modified Electrode
Song Qu, Supeng Pei and Shuping Zhang
Article first published online: 16 MAY 2013 | DOI: 10.1002/jccs.201200543
A novel Silicate nanotubes (SNTs) modified glass carbon (GC) electrode was prepared and used to study the electrochemcial behavior of phenylephrine (PHE). The enhanced electrochemical response of PHE at SNTs modified electrode was observed as compared with bare GC electrode. Our present study may provide an alternative way for the application to the electrochemical sensors.
- Catalysis of Multi-walled Carbon Nanotubes Supported PdxCoy Nanoparticles Prepared by a Pyrolysis Method Using Ionic Liquids as the Solvent toward Ethanol Oxidation Reaction

Multi-walled carbon nanotubes decorated with PdxCoy nanoparticles were fabricated by a simple pyrolysis process using ILs as the solvent. Results show that the PdxCoy nanoparticles were uniformly dispersed on MWCNTs. And the onset potential was ∼90 mV lower and the peak current was about four times higher for ethanol oxidation for Pd3Co1.5/MWCNTs compared to those of Pd3Co1/MWCNTs.
- Convenient Synthesis of 14-Aryl-14-H-dibenzo[a,j]xanthenes Catalyzed by Acyclic Brønsted Acidic Ionic Liquid [H—NMP]+[HSO4]− under Microwave Irradiation

Efficient method for direct preparation of 14–aryl–14–H–dibenzo[a,j]xanthenes through condensation of β–naphthol with various aromatic aldehydes in the presence of the catalytic amount of [H—NMP]+[HSO4]− under microwave irradiation was described. This method has the advantages such as; very easy reaction workup, absolute separation of catalyst from the reaction mixture and smooth recyclability of catalyst.
